When an exclusive fullscreen display is specified, it overrides any positioning, including from driver specific functions. Allows for the proper placement of fullscreen windows on macOS and Windows when the floating window is on a display that differs from the one specified by the exclusive fullscreen mode.
A specific position-only function has been split out for use when a window has been moved.
`EM_ASM_` and `EM_ASM_INT_V` are calls that have been deprecated
for a long time.
Since the return value isn't used for the call to `EM_ASM_`, it
can be replaced with `EM_ASM`.
`EM_ASM_INT_V` is now (for the last few years) `EM_ASM_INT`.
A window 1920x1080 pixels wide at 125% scaling will have a width and height of 1536x864, but at pixel (1919,1079) the mouse coordinate will be (1535.2,863.2), which is within the bounds of 1536x864, but larger than (1535,863).
This takes care of the last set of void functions that could
potentially be shifted to instead return an int indicating success and
setting an error in case of an error.
This function wasn't consistently correct across platforms and devices.
If you want the UI scale factor, you can use display_scale in the structure returned by SDL_GetDesktopDisplayMode(). If you need an approximate DPI, you can multiply this value times 160 on iPhone and Android, and 96 on other platforms.
The Xrandr dot clock value is declared as an unsigned long and the result when multiplying by 100 can overflow on a 32-bit system. Explicitly cast it to Sint64 to ensure that no overflow will occur.
Attempt to retrieve the display for fullscreen windows using the window position so that the correct display ID is returned if an exclusive fullscreen window is moved to another display.
* Setting the same mouse cursor twice is a no-op
* Cocoa: Call [NSCursor set] to change mouse cursor
The previous way, changing the mouse cursor was handled by invalidating
the mouse cursor rectangles and then recreating them (with the new
cursor) the next event loop. This is extremely slow; sometimes it can
take over a millisecond! With [NSCursor set] it happens instantly and
very quick performance-wise.
The downside is that it sets the cursor for the whole screen, so we
have some guards in place to change it to the system cursor if
the mouse moves outside the window or the window loses focus.
* Cocoa: Remove unneeded resetCursorRects: function
Without these mappings, this controller "kinda" works out of the box:
- `SDL_GameControllerMapping()` works because it will notice "Xbox" in
the name and use the default XInput mappings
- `SDL_GameControllerMappingForGUID()` will not find any mapping
lsusb:
```
ID 2dc8:2000 8BitDo 8BitDo Pro 2 Wired Controller for Xbox
```
In Linux this controller is supported by two drivers:
- `xpad` (built-in to the kernel), exposes the controller name from the
USB descriptor and the GUID starts with 03 (0x03 = BUS_USB)
- `xone` (https://github.com/medusalix/xone), exposes a virtual
controller which is always named "Microsoft X-Box One pad" and the
GUID starts with 06 (0x06 = BUS_VIRTUAL)
This commit adds the 2 GUIDs from both drivers so mappings will always
be found and the real controller name will always be reported.

Portrait displays may have native, physical resolutions that are taller than wide. Reverse the mode dimensions when dealing with these displays as well as those rotated via software means.
